Recently Professor Lee has suggested the analysis of the indicative conditional based on Sellars-Brandom's inferentialism. In this paper, I raise three questions. First, Professor Lee seems to misunderstand Sellars-Brandom in that he considers only the analytically valid arguments as materially valid inferences. Second, Professor Lee seems to misunderstand Sellars-Brandom in that whereas Sellars-Brandom talks about the common features of all kinds of conditionals including counterfactual conditionals, Professor Lee takes it as the analysis of the indicative conditional only. Third, either Professor Lee's analysis is incompatible with Sellars-Brandom inferentialism or his analysis is too general.

In a previous paper I argued that the denial of the uncontested principle results in the denial of modus ponens. In his reply Byeong Deok Lee explicitly says that he does not deny the validity of modus ponens though he still does not accept the uncontested principle. In this paper I show that his view is untenable.

Recently Byeong Deok Lee has denied the validity of the so-called uncontested principle, which says that the indicative conditional implies the material conditional. I show that his denial means that modus ponens is not valid and that the truth-conditions of indicative conditionals are weaker than that of material conditionals. It seems that what made him hold this view is related to some misunderstanding of indicative conditionals.
